Undefined reference to vtable

Question

When building my C++ program, I\'m getting the error message

undefined reference to \'vtable...

What is the cause of this probl

Answer 1

For what it is worth, forgetting a body on a virtual destructor generates the following:

undefined reference to `vtable for CYourClass'.

I am adding a note because the error message is deceptive. (This was with gcc version 4.6.3.)
